Specification of Letters Patent...

Patented April 20, 1 909.

) Applic'ation filed June so, 1905. Serial no. 267,812.

.' State of New'Yorlghave invented certain .new and useful Improvements in Type- -Writing Machines, of which the following is a specification.

My invent' n-relates to typewritin machines and more especially to tabu ating mechanism forsuch machines.

My invention has for its principal ob'ect to provide animproved denominational tab ulator. q

My invention consists in certain features of construction and combinations and arrangements of arts which will be fully set forth herein an particularly pointed out in the claims.

-111 the accompanying drawings, Figure 1 is a side elevationof a typewriting machine having myinvention applied thereto, the 7 main framebeing shown in section j11st in side of the right-hand Slde plate. ,.F1g. 2 1s a top plan view, most of the upper art. of the t ewriter mechanism being bro en away F i 3 is a rear elevation, the base of the machine being shown in section on the line as m of Fig. 1. Fig. 4 is a diagrammatic enlarged end' view of the drum that carries the denomination stops. Fig. 5 is a diagrammatic view-showinga development of the interior of said drum. 1

In most of the views ted or broken away or s been foundconvenient.

I have shown-m invention applied to the Monarch-front-stnke typewriter, but it will be obvious that said invention may be adapted to other styles oft ewriting machines.

The main frame of t e machine shown in parts have been omitown 1n section as has the drawingscomprises a base portion '1.

from which rise posts 2 that support a top plate 3. Two posts 4, rising from said top 7 plate, support stationary rails 5 which are grooved to coo crate with anti-friction balls or rollers 6,-w ich support a carriage" 7 by means of grooved rails 8 forming'part of said carriage. A platen 9 is'mounted 1n said carriage. The carnage is drawn across the ma chine by a spring drum 1O acting through a strap 11 which is connected "at one end to said drum-and at the other end to the carriage. Afeed rack 12 is mounted on arms 13 that are-pivoted at 14 to the carriage. Said feed rack is pressed b springs 15 into engagement with a fee( pinion 16 which is mounted on the forward endof a shaft 17 which is journaled in a bracket or housing 18 mounted on the top plate 3. At its rear end the shaft 17 carries an escapement wheel 19 which is controlled by feed dogs 20 mounted on an arm 21 that rises from a horizontal rock shaft 22 that is pivoted on pivot pins 23. mounted in a bracket 24 that de ends from the top plate 3. The arm 21 an rock shaft 22 form parts of a dog rocker which also has a forwardly extending arm 25 having at'its end laterally spreading arms 26 which are connected by links 27 to a universal bar 28, which lies beneath a series of key levers 29. The key levers 29 arepivoted at 30 and at their forward endscarrv character 7 keys 31. Each of said key levers has pivoted thereto a sub-lever 32 which is connected by a link 33 with one of a series of type bars 34 which are pivotally mounted in a type bar segment 35. The parts above referred to are of known construction, and so far as my invention is concerned they may be of any suitable construction. The main frame of the machine also comprises a, cross-bar 36 which joins the two side plates of the base portion of the machine just back of the keycard and above the key levers and a second cross-bar 37 which joins said side plates near the middle of the machine.

- My tabulator mechanism comprises a series of key levers which are mounted in a frame detachably secured to the cross bars 36 and 37 above the key levers 29 and below the type bars 34. Saidrframe comprises a front bar 38 which lies on the cross bar 36 and two side bars 40 which extend toward the rear of the machine from said front bar. Said front bar is secured to the frame bar 36 by screws 41.. The key levers 42 are pivoted at their rear ends on a rod' 43 which is mounted at its ends two brackets 44 which rise from the side bars 40 of the key lever frame. Said rod asses through openings in said brackets and is secured in place by set screws 45 which are threaded through the brackets and engage the rod. Near their forward ends the key levers 42 pass through a slotted plate 46" which is secured to the frame bar 36 by screws 47. The key levers 42 carry tabulator keys 48 on the forward ends, said keys'being arranged in a row back of and above the character keys 31. The downward motion of said key levers is limited by the lower endsof the slotsin the plate 46. Said key levers are returned to normal which secured to the crossbar 37 by screws 51. he forward ends of the springs 49 press up the sides of the key evers 42. 'l. he plate 50 is slotted and constitutes a comb .plate to guide the rear ends of the key levers 42.

The several keys 48 are, adapted to move .a rocking frame different distances in order to set the tabulator stops to arrest the carriage vin different positions. Said rocking frame comprises a rock shaft 53 pivoted on the reduced ends of pivot screws 54 which are threaded through cars 55 de ending from the side bars 40, just back-of t e frame bar on which the key levers are pivoted, than the. other end and also farther from the pivotal axis of the frame itself Adjustable contact screws are threaded through the bar 59, one beneath each of the key levers, and in position to be enga ed by said key levers when the latter are epressed. The relation between any key lever and the rock frame may be regulated by adjusting the appro priate screw 60.

An arm 61 projects from the rock shaft 53 toward the back of the machine, its rear end lying beneath the frame bar 37. For the sake .of rigidit the arm 61 is connected to the arm 58 an bar 59 by a bracket 61 The free end of said arm 61 has pivoted thereto at 62 the lower end of a link 63 which extends upward and toward the rear of the machine through a suitable opening in the cross bar 37 andthrough a suitable opening in the to plate 3. The up or end of said link 63 1s pivoted by a shou dered and headed screw 64 to a segmental rack 65 which isjournaled on a shouldered and headed screw 66, which is threaded into a flat portion 67- of one of the posts 4 that support the stationary rails for the carriage. The link 63 consists of two parts which are connected together by a turnuckle 68 by adjusting which the length of the link may be varied. A returning spring 69 is coiled-"about the link 63 and is comressed between the upper surface of the frame bar 37 and a washer 70 which surrounds the link 63 and lies against the turnbuckle 68. The rack 65 meshes with apinion 71 rigidly mounted on one end of a tabulator bar 7 '2 which is rotatably mounted in brackets 73 which project toward the rear of the machine from the posts 4. At the end of the osition by springs 49; which are secured at t eir rear ends to a plate the machine. ard on ms 52 projecting from tabulator bar, opposite the pinion 71 said tabulator bar is journaled in a sleeve 74 which is threaded through the bracket 73 and is adjustable therein, so as to regulate the position of the tabulator bar width-wise of Said-tabulator bar is formed on its front and rear sides with slots 75 spaced a letter space distance apart, and tabulator sto pieces 76 are adapted' to be mounted on sai tabulator bar and positioned by said slots. Said stop pieces-have the form shown in Fig. 4, that is to say, they are U-shaped. and are adapted to straddle the bar 72, entering the slots 75. Each of said stop pieces has projecting therefrom a lug or arm 77 which constitutes a column stop. v

The denomination stops consist of a series of lugs 78 projecting inward from the inner surface of'a cylindrical drum or barrel 79 which, as best shown in Fig. 2, is mounted on an arm or bracket 80 projecting toward the .rear of the machine from the carriage 7 to which it is secured by screws 81 (Fig. 3). The drum 79 surrounds the tabulator bar 72 and is-concentric therewith. The denomination stops 78 are spirallyarranged within said drum,

said stops being spaced a letter space distance apart along the axis of the drum, and

being uniformly spaced around the drum except that in the space normally occupied by the column stop 77 there is no denomination stop 78. Inithe normal position of the parts shown in Fig. 4 the drum 79 is free to travel back and forth with the carriage Without striking any of the column stops, but if the bar 72 be turned outof its normal position it will bring the column steps 77 into the path of one or another of the denomination stops and said column stop will be in position to arrest the carriage in a column the'position of which is determined by the position of the column stop on the bar 72 and at adenominational position within said column determined by the extent to which said bar has been rotated away from its normal position. When any tabulator key is depressedthe key lever 42 engagingits screw 60 will depress the frame bar .59 and rock the shaft 53 through a distance depending upon the key depressed The motion of the rock shaft 53 will be communicated throughthe arm 61, link 63, segment 65, and pinion 71 to the tabulator bar 72 and will bring the tabulator stops 77 into the path of that one of the denomination stops 78 which corresponds to the key depressed.

. In order to release the carriage by the depression of any'of the tabulator keys, each of the key levers 42 is prolonged so as to extend back of the pivot 43 and a universal bar 82 is provided, said universal bar lying across the rear ends of all of the key levers. The universal bar 82 is carried by arms 83 proj ectingj from a rock shaft 84 which lies above the pivot rod 43 and is pivoted on pivot pins the patlmithe selecteddenomination stop 78.

enema 85 which project ets 44 and are secured in osition by set screws 86. Each of the key evers 42 has an 84 and said arm has pivoted "connectedjat -91 to a rack tends'upward through an opening 93 (F 2);

adjusting screw 87 threaded through its rear end and it is the end of this screw that contacts with the universal bar when the key is depressed. The relation of each key to the universal bar may be regulated by adjusting the screw 87. An arm 88 projects toward the rearofthe machine from the rock shaft to its rear end at 89'ari upwardly. extendin link 90 which is in the top plate 3. The upper end of the rack lifter-92 is forked, as shown in Fig. 3, tostraddle the reducedforward end of the hous-t ing 18 in which the...escapement wheel shaft T 17 is'journaled. Each of the forks ofthe which raises the feed rack 12 out of enga' e ment with thepini'on 16, thus releasing tAe t ator bar 72 is rotated racklifter is bent toward the front of the machine, as shown in Fig- 1., and lies beneath the feed rack 12. The construction is such t at when any tabulator key is depressed the through the link 90elevates the rack lifter,

carriage from its es'ca ment' devices. the same time the tab by the key to bring the column stop 77 into Various changesmay be made in the do tails of constructlon and arrangements without departingfrom my invention.
